CAUTION:
 The spiral cable may snap by steering operation if the cable is
installed in an improper position.
 The neutral position is set as follows. Turn quietly the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and half turns) and
stop turning at the point on which the stopper insertion holes
are in the same position.
The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper is
removed.
 Do not turn the spiral cable r ashly and also beyond the limit
number of turns. (These will cause cable snap.)
 Adjust the spiral cable locating pin (showed as A inthe figure) to the steering wheel locating pin hole (showed as C in the
figuer).
 Secure the air bag harness wi th the harness fixing hook.
 After the work is completed, make sure no system malfunc- tion is detected by air bag warning lamp.
 In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis function and delete the
memory by CONSULT −III.
 In case that malfunction is still detected after the above opera-
tion, perform self-diagnosis to repair malfunctions. Refer to
